BACKGROUND

The subject disclosure relates to computer architecture, and morespecifically, to deep learning systems. Deep learning is a machinelearning technique that employs a training process associated with anetwork of processing layers (e.g., an input layer, a set of hiddenlayers and/or an output layer) to determine previously unknown features,classifications and/or patterns associated with data provided to thenetwork of processing layers. Deep learning is often employed intechnical fields such as, for example, speech recognition, imagerecognition, video processing, text analysis, graphical modeling, dataanalysis, bioinformatics, technical systems associated with unstructureddata, and/or other technical applications. Data provided to the networkof processing layers can include a training set (e.g., a set of datawith known classifications that is employed for the training process)that is employed at a beginning of the training process. Utilizing thetraining set, the network of processing layers can perform iterativeprocessing stages in which data generated during a particular processingstage is determined from data generated during one or more previousprocessing stages. During a processing stage, processing layers canindependently generate data based on input data and/or previouslylearned data. In certain implementations, a graphics processing unit canbe employed to execute deep learning. For instance, a graphicsprocessing unit can be employed to execute the network of processinglayers. In one example, Yang et al. (U.S. Patent Publication No.2016/0342888) discloses “techniques that improve performance of CNNsystems through the effect of improved memory efficiencies for CNNsoperating on GPUs.” However, a graphics processing unit generally haslimited on-board memory. Furthermore, a graphics processing unitgenerally cannot accommodate certain types of deep learning networks(e.g., a large deep learning network, a complex deep learning network,etc.). As such, deep learning associated with a graphics processing unitcan be improved.

DETAILED DESCRIPTION

The following detailed description is merely illustrative and is notintended to limit embodiments and/or application or uses of embodiments.Furthermore, there is no intention to be bound by any expressed orimplied information presented in the preceding Background or Summarysections, or in the Detailed Description section.

One or more embodiments are now described with reference to thedrawings, wherein like referenced numerals are used to refer to likeelements throughout. In the following description, for purposes ofexplanation, numerous specific details are set forth in order to providea more thorough understanding of the one or more embodiments. It isevident, however, in various cases, that the one or more embodiments canbe practiced without these specific details.

Deep learning is a machine learning technique that employs a trainingprocess associated with a network of processing layers (e.g., an inputlayer, a set of hidden layers and/or an output layer) to determinepreviously unknown features, classifications and/or patterns associatedwith data provided to the network of processing layers. Deep learning isoften employed in technical fields such as, for example, speechrecognition, image recognition, video processing, text analysis,graphical modeling, data analysis, bioinformatics, technical systemsassociated with unstructured data, and/or other technical applications.Data provided to the network of processing layers can include a trainingset (e.g., a set of data with known classifications that is employed forthe training process) that is employed at a beginning of the trainingprocess. Utilizing the training set, the network of processing layerscan perform iterative processing stages in which data generated during aparticular processing stage is determined from data generated during oneor more previous processing stages. During a processing stage,processing layers can independently generate data based on input dataand/or previously learned data. In an embodiment, a graphics processingunit can be employed to execute deep learning. For example, a graphicsprocessing unit can be employed to execute the network of processinglayers. However, a graphics processing unit generally has limitedon-board memory. Furthermore, a graphics processing unit generallycannot accommodate certain types of deep learning networks (e.g., alarge deep learning network, a complex deep learning network, etc.). Assuch, deep learning associated with a graphics processing unit can beimproved.

To address these and/or other problems associated with conventional deeplearning techniques, deep learning that employs a graphics processingunit, and/or other conventional technologies, embodiments describedherein include systems, computer-implemented methods, and computerprogram products for model support in deep learning. In an aspect,graphics processing unit can be employed for deep learning to providemodel support. The model can be, for example, a deep learning model.Furthermore, a host memory can additionally be employed to provide themodel support. The host memory can be, for example, a central processingunit memory.

However, it is to be appreciated that the host memory can be adifferent type of memory. The host memory can be communicatively coupledto the graphics processing unit. The host memory can be employed as acache for deep learning associated with the graphics processing unit.For example, the host memory can be employed as a cache to store atleast a portion of data associated with training of a deep learningmodel for a deep learning network executed by the graphics processingunit. In an embodiment, data from a forward pass associated with a deeplearning network executed by the graphics processing unit can be reusedin a backward pass associated with the deep learning network executed bythe graphics processing unit. The data from the forward pass can bestored in the host memory. Furthermore, during the backward pass, thedata stored in the host memory can be provided to the graphicsprocessing unit. The forward pass can be a forward pass process of thedeep learning network that traverses through a set of layers for thedeep neural network from a first layer of the set of layers to a lastlayer of the set of layers that provides a set of outputs for the deeplearning network. The backward pass can be a backward pass process ofthe deep learning network that traverses through the set of layers forthe deep neural network from the last layer of the set of layers to thefirst layer of the set of layers. In another embodiment, after thebackward pass is completed, at least a portion of the data can bediscarded from the host memory. Additionally, in certain embodiments,the graphics processing unit can provide the data to the host memory viaa compression scheme. Accordingly, processing performance of thegraphics processing unit can be improved, computing bottlenecks of thegraphics processing unit can be reduced and/or processing efficiency ofthe graphics processing unit can be improved. Furthermore, a batch size(e.g., a number of training elements for a forward pass or a backwardpass) for a deep learning network and/or an amount of data processed bya deep learning network can be increased. Moreover, an amount of time toperform deep learning associated with a deep learning network can bereduced.
